T 0 all whom it may concern:

Be it known that l, ADOLII HUBER,'B, citizen oi Austria, residing at Hartford, in the county of l-lertiord and State of Connecticut, have invented s new and useful Look, of which the following is a specification.

This invention relates to an improvement in tumbler looks and while the embodiment of the invention is illustrated and desoribed herein as designed in the "form of n trunk or chest look, the invention is not limited to such a. type of lock for by simply chan ing the form of the casing it can be adsptet for use as a door, desk or cabinet look.

The ob'ect oi the invention is to provide a look which when closed exposes no means by which it pen be opened and when the'rneens for opening it are exposed requires fieculiar manipulation before the key will engage and move the bolt, and then requires a pertieular number of turns of the key before the bolt is shot sufliriently to release the hosp or other part which the bolt engages for looking.

The trunk look shown hes a keyhole cons ceoled beneath it lid which has no appsrent' means {)y whioh it (on he opened but which springs open when the plate or a humming: of the plate is pushed so as to re lease e outoh which holds the keyhole lid closed. The key when inserted in the keyhole that is exposed by the sprin ingj open of the and holds it test.

lid, turns around idly until. zillor the key-pintle is pressed inwardly by any means so {IS to release a tumbler that is rnrried by the bolt and with Wlilili tunihler the bit of the key must engage and move the bolt into such position tlmt the subsequent turns of the key will lift the looking tumbler and shoot the bolt. When the bolt is to be looked the hey is Given one turn to shoot the bolt so-thut it will engage the beep or otherlocking port and then given at second turn to iurthvrshoot the bolt and iinnily :1 third turn whi'ch. lifts the lilllllbifil ('nrriod by the bolt until it is enaged by n s wing pin connected with the (ey-pintlo, wldoh notch must be releasedl'i'om the bolt tumbler before the key can nmiin IHUVO the bolt in either direction. A 'l'ter the key is removed from the lock the lid is closed over the keyhole until the catch connected with the Figure 1 of-the accompanying drawings shows a side view of n lock with the ports closed and fully looked. Fig. 2 is a. similar looked. Fig. 5 is a similar view with the the lit plate trnnining engages View with the hoop removed and tlie'liil olpened so as to expose the keyhole. Fig.3 s ows a rear View of thelook. 4 shows a rear view of'the locking mechanism with the ports in the positions occupied when ports in the positions occupied sit-er the he pintle has been pressed so as to release .t .e

tilt-throwing tumbler. Fig-6 is a sectional View taken on the lane indicated by the dotted lineon Fig. 3. Fig. 7 is s VIEW of the bolt. Fig. 8 is e view'oi' the bolt tumbler.- And 1F lg. 9 is it View of the locking tumbler.

The lock is shown in the views mounted in on the heels: of e fees lete 1 which is adapted. to be secured to the one of a. trunk, chest or; other par This form of look. hes a has 2 that s desi nod to be fastened tothe li orf other part t at is to be lifted. The lmsp has a. common soolcet or loop which is s-d'er ted to catch pin Y'thot projects from/the heck of through t is mounted on the back 0= the face plate.

is opening 8 m the fees plate is released from the spring her 9 that (lne end of this spring: bar is connected by a pin 11 with one of the trimmings 12 on the "ihe springer-i? this corner of the fore pinto. bar normally holds it in such position that it will vngnge'the pin 7 on the book of the lid. When the trimming is pushed down-- wurdly the bar is moved from the pin so that; the spring will throiv the lid open. -When thelid is closed thereis noapparent means connected with it or on the fare of the plate by which it can be opened.

The bolt 1'3 is inovshly the strap 14 end thebeckplate 15. Onone edge of the holt'is 21. looking shoulder Miami it looking shoulder 17.

ads ted to be engaged by the hooked'end of I the oeking tumbler l8 which-hes an arm 19 that extends between the "bolt and thefnce plate into position. to be lifted by the bit of the key when the key is turned. When the 110/ heldin place by I These shoulders ere.

bit of the key lifts the arm and lockingand which is engaged by the bit of the key for moving the bolt one step in its locking movement and it has a shoulder 24 which coincides with a shoulder on the bolt and which is engagediby the bit of the key on its second turn for moving the bolt the second step ofitsflloeking n'iovement. The tumbler has an arm 25 that extends below the bolt and that on the third turn of the key is engaged by the bit and is lifted to the position shoWndn-Fig. 4 in which position it is en aged and held by a stud 26 that is mounte d on a spring plate 27 fastened'to the back face of the back late. When this tunibler is held lifted in 't is manner the bit of thekey will turn around without engag ing the tumbler or any shoulder on the bolt.

Fastened to the back face ot the back plate is a spring plate 2 8 that extends beneath the spring plate 27. Fastened to this spring plate 28 is'tli'e key-piritle "29 that projects forw ardly into the keyhole and upon which. the key turns. lVhen the key-pintle is pressed backwardly with. sufficient force the spring plate 28 pushes backwardly the spring plate '27 and Withdraws the catch stud 26 from engagement with the tumbler 21' allowing that tumbler to be thrown down into the position shown in Fig. 5. When the tumbler is, in. this position the first backward turn of the key engages the shoulder 30 and Withdraws the bolt one step. The next turn of the key will engage the shoulder 31 on the tumbler and a coinciding shoulder on the bolt and moves' the bolt the next step.

It takes three turns of the key to fully lock the parts, the first turn throws the bolt and bolt tumbler one step, the second turn throws the bolt and bolt tumbler the second step and the third turn lifts the bolt tumbler until it engaged by the catch. As statedil the key is simply inserted in the keyhole it turns idly until the pintle is pressed to release the bolt tumbler. When the key-pintle is pressed and the bolt tumbler is released the first turn of the key en ages the bolt tumbler and draws back the ho t one step and the next turn engages the bolt tumbler and the bolt and witl'idraws the bolt the second step.

The invention claimed is A look having a bolt with a shoulder adapted to be engaged by the bit of the key for moving the bolt one step, a locking tumbler adapted to en a e the bolt and to be disenga ed from the iolt by the bit of the key, a tumi ing a shoulder adapted to beengagecl by the key for moving the bolt one step and a part adapted to be engaged by the bit-of the key and so lifted that the shoulder on the tumbler' will be out of the path of the bit of the key, a catch adapted to engage and tempo rarily hold the bolt tumbler out of the path of the key when-the bolt tumbler is lifted by the bit of the key, a movable key pintle and a connection between the pintle and the catch whereby the movement of the pintle disengages the catch fromv the bolt tumbler and allows that tumbler to be dropped so that its shoulder lies in the path of the bit of the key, substantially as specified.
